- A heteroecious species: primary hosts are cherry and wild cherry (Prunus cerasus and P. avium); secondary hosts are Galium, Veronica, Asperula.
- These aphids overwinter in the egg stage, eggs having been deposited on trunks, branches or buds. Fundatrices emerge in March-April. Several generations follow each other, feeding on the tip of shoots of cherry or on the underside of leaves, causing the leaves to form compact bundles visited by ants.
- Winged aphids emerge in June-July, migrating to secondary hosts on which they will breed. A return migration to cherry takes place in the autumn and winter eggs are eventually laid.
This species freauently causes damage. Depredations occur at the maturation period of cherry, attacks being especially severe on young trees. Leaves curl up, become scabby and form dense bundles (*) . The presence of honeydew causes a scorching of leaves which moreover become dry.
